Most Krav Maga instructors seem to teach a "clinch" or grab for knee strikes that is different from the Muay Thai double neck tie clinch.

I find the Muay Thai clinch very effective if done properly and I have seen it in many full contact Muay Thai or MMA fights. However, I have never seen the above mentioned Krav Maga version in such fights. To me, it seems to provide much less control over your opponent than the Muay Thai clinch. What do you think of the Krav Maga grab for knee strikes? Is it really effective?
